PROBLEM TO BE SOLVED: To provide a drainage device that makes a release wire be easily attached regardless of a situation with respect to, for example, a position at which an operation part is attached.SOLUTION: A lid part 14 for covering a drainage opening 12 of a drainage body 11 includes: an inflow port 15 in which drainage water from a bath tab flows; an attachment hole 16a; and an attachment hole 16b. A worker, in performing construction, disposes an appropriately L-shaped release guide 20 that is disposed on the lid part at any angle in a plan view to guide a release wire inside the lid part, at any attachment hole 16 depending on a situation etc. with respect to, for example, a position at which an operation part is attached; and disposes a check valve 21 for preventing drainage water in the drainage body 11 from reversely flowing onto a waterproof pan, at the other attachment hole 16.SELECTED DRAWING: Figure 3 |
